A Multiple Objective Embedded Network Model for Human Resource Planning and an Implementation of the Tchebycheff Method

A multiple objective embedded network model is proposed to model a variety of human resource planning problems including executive succession planning, compensation planning, training program design, diversity management and human systems design. The Tchebycheff Method, an interactive multiple objective programming solution procedure developed by Steuer and Choo [32], is implemented using NETSIDE, a computer routine for solving network problems with side constraints developed by Kennington and Whisman [17]. This paper demonstrates how the network structure common to many types of human resource planning problems can be exploited to improve solution efficiency, and how our approach extends the use of network models in human resource planning by including multiple objectives and extranetwork constraints. An illustrative example demonstrating the modeling and solution approach is presented, and the potential applications of these approaches in two specific areas of human resource planning are discussed.     

Competitive procurement strategies: Building strength and reducing vulnerability

Current economic conditions and resource constraints call into question many of the implicit assumptions to which traditional strategic planning models subscribe. An attempt is made to bridge the gap between product/market decisions and concerns for present and future resource availability. The author develops the notion of strategic procurement planning as an approach to make more salient the potential competitive ramifications of procurement related decisions and for better integrating purchasing into the corporate planning process.     

Guidelines for contingency approach to planning

In an earlier article the author discussed the contingency approach to planning as a flexible managerial tool making it possible to find a good fit between the planning process and the organization. In the present article the contingency approach is applied to the product life cycle to show how the different steps in the planning process can be varied as the situation changes. The contingency approach to planning can be used in a similar fashion for a product line, a product division, or the entire organization.     

Planning for water resources

In this article the author describes some of the problems of planning for water resources, and the way in which the recently established Thames Water Authority has organized itself to deal with them. He demonstrates that water resource planning is involved with the whole of the water cycle, and is largely concerned with harnessing and controlling natural phenomena in situations of uncertainty.     

Aggregate production planning with workforce transferring plan for multiple product types

This paper presents the aggregate production planning for multiple product types where the worker resource can be transferred among the production lines. A mathematical model was formulated in spreadsheet format. Then the spreadsheet-solver technique was used as a tool to solve the model. A real situation of a manufacturing company was selected as a case study. The actual data was used to test and validate the proposed model. The optimal aggregate production plan provides the information on managing the available production capacity together with the useful workforce transferring plan. The obtained solutions were compared to those of another approach where the workers cannot be transferred among the production lines. The total cost is significantly reduced when the workers are allowed to transfer among the production lines.     

Land use planning: An optimizing model

An optimizing model for comprehensive land use planning (OPTPLAN) is described. Multiple objectives and constraints on desired growth patterns are considered simultaneously in arriving at optimal acreages of ten land use types in several regions within a county or city. Objectives are (i) minimization of conflict between different land uses, (ii) minimization of travel distance of new trips to the existing transportation network, (iii) generation of a fiscally sound plan, and (iv) minimization of environmental impact. Constraints are on each type of land use based on population and employment projections, projected mix of residential dwelling units, local commercial and institutional land needed per thousand persons, location and extent of new industries, open space requirements per thousand population, and natural resource considerations. Application of the model to Du Page County, Illinois is shown.     

Genetic algorithm to production planning and scheduling problems for manufacturing systems

Fundamental and extended multi-objective (MO) models are designed to address earliness/tardiness production scheduling planning (ETPSP) problems with multi-process capacity balance, multi-product production and lot-size consideration. A canonical genetic algorithm (GA) approach and a prospective multi-objective GA (MOGA) approach are proposed as solutions for different practical problems. Simulation results as well as comparisons with other techniques demonstrate the effectiveness of the MOGA approach, which is a noted improvement to any of the existing techniques, and also in practice provides a new trend of integrating manufacturing resource planning (MRPII) with just-in-time (JIT) in the production planning procedure.

A concept of an integrated transport model

This paper is one of a series being produced on the application of Operational Research techniques in the integrated planning of public service resource provision and consumption. It describes a conceptual basis for planning transportation services within the context of a public service, the others are related to Health Services, Educational Services and community development services.Two sub-models, a linear sub-model and a dynamic sub-model are linked to form the integrated approach to the planning problem. The overall concept is to evaluate in terms of penalties and benefits the alternative plans of resource provisions.It is of interest to know that the principles of the Linear model described here has been applied to long range planning in the Health Service in the U.S.A. and U.K., and has been reported at the NATO conference, Portugal (1974). The Dynamic model has been used, in a more unstructured fashion than described here, by the Greater London Councils. The model in this paper is to form the basis of a more detailed evaluation of alternative transportation plans.     

Criteria for selecting a production control philosophy

Logistic objectives constitute a compromise between having short leadtimes and a low volume of work in progress on the one hand and a high resource loading and due date obligation on the other. Miscellaneous production planning approaches offered today provide different combinations of logistic objectives for satisfying a manufacturing strategy. To combine the strength of the various approaches into a unified system, a new approach based on a dynamic and distributed production planning methodology is proposed. To customize the approach, various analyses and specifications have to be made and for that reason some important characteristics and criteria for analysing production control philosophies will be given.     

Comprehensive planning for libraries

In the area of planning, the literature has been almost entirely concerned with planning in the business (i.e. profit) setting. Some literature does exist on planning in the nonprofit sector, but it usually deals with tactical planning of the short-term character. This is specially true in the area of libraries and many librarians have developed and do administer large, complex organization— where conprehensive, long range planning is almost completely untreated in the literature.The current paper discusses the various steps in the strategic planning process, and relates them to a situation in which comprehensive long range plans for a new health sciences library have been developed, and to a considerable degree, implemented. In this framework, the steps of developing purpose and objecives, forecasting and policy formulation, developing and choosing growth strategy, determining resource requirements and provions, developing an organizational structure, and control system utilization are discussed both in the general framework of comprehensive planning, and with respect to actual experience in the development of a health sciences library. The roles of tactical planning and the implementation of plans are also treated.     

AN ADAPTIVE DECISION SUPPORT SYSTEM FOR ACADEMIC RESOURCE PLANNING

Institutions of higher learning are growing increasingly interested in the use of model-based approaches to their resource allocation problems. Recent modeling approaches, however, have failed to consider that resource allocation planning is not a well-structured decision process. Additionally, many decision makers are necessarily involved in the academic planning process and may assume dissimilar perspectives on the importance of achieving different goals and objectives. Furthermore, satisfactory allocation solutions can be expected to vary considerably from decision maker to decision maker as the individual's cognitive processes, perceptions, and evaluations are taken into consideration. This paper describes a decision support system (DSS) approach that attempts to adapt to a variety of academic decision makers with differing planning views in an environment of multiple conflicting objectives. This DSS, which was successfully tested on four academic decision makers in a large midwestern university, shows considerable promise for providing decision support to decision makers with varied problem-solving styles.     

EDUCATION

The power of an integer programming approach—and more particularly a 0,1 programming approach—to resource allocation problems is not widely appreciated. Recent developments in mathematical programming and in problem formulation enable decision makers to deal explicitly with the special conditions which characterize real world problems in capital budgeting, scheduling, and facilities planning. In this paper, somewhat tutorial in nature, we seek to demonstrate formulation and solution of an equipment selection resource allocation problem with several special conditions. The problem can be solved on any reasonably equipped computer system. Sensitivity studies are also performed and discussed.     

A TUTORIAL ON BOTTLENECK DYNAMICS: A HEURISTIC SCHEDULING METHODOLOGY

We give a tutorial on bottleneck dynamics. Bottleneck dynamics is a scheduling framework that uses approximate dual resource prices to make decentralized decisions. The basic idea is to establish a price for a resource as a function of the set of jobs that need to be processed by the resource. Tasks are then sequenced according to a cost/benefit ratio. Starting with one resource sequencing problems, we describe how priorities for jobs can be developed and how they translate into resource prices. We then describe how resource prices can be approximated in a multiresource situation and how lead times which are critical for these approximations can be accurately computed. We also describe a number of studies that have shown bottleneck dynamics to be an effective approach in several different problem areas.     

Multi-site aggregate production planning with multiple objectives: A goal programming approach

This paper addresses the problem of aggregate production planning (APP) for a multinational lingerie company in Hong Kong. The multi-site production planning problem considers the production loading plans among manufacturing factories subject to certain restrictions, such as production import/export quotas imposed by regulatory requirements of different nations, the use of manufacturing factories/locations with regard to customers' preferences, as well as production capacity, workforce level, storage space and resource conditions of the factories. In this paper, a multi-objective model is developed to solve the production planning problems, in which the profit is maximized but production penalties resulting from going over/under quotas and the change in workforce level are minimized. To enhance the practical implications of the proposed model, different managerial production loading plans are evaluated according to changes in future policy and situation. Numerical results demonstrate the robustness and effectiveness of the developed model.     

Improving human resources for health planning in developing economies

There is a universal consensus that human resources represent the heart and soul of effective health systems everywhere. However, despite this consensus, human resource planning in low income countries remains a neglected, often poorly implemented and ineffective component of health-system development. The planning exercises that do take place are often inefficient, use inappropriate planning models or fail to adequately prioritize human resource investment decisions. This article briefly discusses possible reasons why this failure occurs and describes four key steps that can help health system planners more effectively prioritize and link human resource for health investment decisions to health system strategy and programmatic initiatives. Implications for human resource development practice and national human resource development are discussed.     

Resource management schemes

Every large management organization undergoes the cyclic progress of planning, programming, budgeting, and rating of work tasks of projects to be accomplished by priority in the light of resource constraints controlling personnel strenghts and operating funds by fiscal periods. This is true, especially of governmental departments that are commodity oriented. There must be some ultimate goal of fine grain visibility that management can attempt to achieve or at least approach in order for the functional directors within the organization structure to relate and report most readily to provide required data for proficient resource management. Two essential requirements are visibility and integrated reporting as herein prescribed. Following the ascertainment of resource requirements in the light of projected work effort, some logical procedure should be employed in the rationale of resource adjustments. The Tolerance Box technique is herein described.     

Economic analysis of public water supply in the Piscataqua river watershed

The southeastern portion of New Hampshire is experiencing a rapid growth in population. Many small semi-rural communities are becoming suburban complexes with mushrooming residential developments. These communities are, as a consequence, confronted with expanding demands for municipal services. The situation creates an urgent need for planning efforts that will aid decision makers in the choice among alternative systems for providing these municipal services.

The authors were aware of these needs and were interested in the economic problem involved. Little guidance is to be found in the literature, since most approaches are based on the technical engineering aspects of design and construction. It became apparent that little had been done to combine engineering design and economic evaluation in a comprehensive approach.

The intent of this paper was to analyze the water supply system problem from an economic viewpoint. The study reviews the characteristics of water supply systems and identifies the economic problems associated with them and is, then, primarily an exploratory study conducted on a theoretical basis. It is not a research study in the sense of conducting an analysis or analyses of empirical data.

This exploratory study will hopefully provide a basis for the conduct of future research and the development of some quantitative procedures that will be useful to planners and decision makers.     

A LINEAR PROGRAMMING MODEL OF RESOURCE ALLOCATION IN A UNIVERSITY*

This paper describes the application of a linear programming model to the process of resource allocation at Illinois State University. The model developed is a general model designed to assist academic administrators in allocating the scarce resources at their disposal. The model, and the assumptions upon which it is based, may be altered to suit the particular decision criteria of any particular academic institution. The linear programming model developed here maximizes an objective function which reflects the total net social profit realized by the university on its outputs to society. This objective function was maximized subject to a myriad of constraints which reflected the limitations of budget, space, and other scarce inputs. Further, the constraints reflect the joint interdependency of many parts of the university and the particular educational delivery system employed by a given department. The outputs of the model include the optimal mixture of academic outputs by the university, the optimal distribution and usage of inputs inside the university, and the shadow price of each input. While the linear programming model developed here is general and may be applied to any university, it was applied to Illinois State University in this paper. In the case of Illinois State University, the model recommended a substantial reduction in emphasis upon teacher education.     

The Role of Operational Interdependence and Supervisory Experience on Management Assessments of Resource Planning Systems

Greater interdependence among workers and activities not only increases the need for internal communication, but it also imposes complications and barriers to effective information exchange. Intraorganizational communication capabilities of certain information systems can help overcome these barriers. However, the extent to which certain systems are promoted as communication tools depends largely on management's interpretation of their usefulness, which in turn may be largely dependent on operational context and managerial experience. We use a controlled experimental approach to study how these issues interact to impact managerial assessments of resource planning systems. Results show that managers value the communication capabilities of resource planning systems more so in highly task‐interdependent contexts and that these assessments are still more positive among managers with greater supervisory experience. As a result, these findings pose direct implications regarding the management support of technology use.
